Find users near your position

I'm looking for a way to find users in a certain radius of your position. The reason I need this is because I want to know how many people there are in an area. A possible way I found is to activate the bluetooth and find active devices around.

I want to know if there are other solutions, API, possibilities to do this.

Your best bet would probably be with searching for bluetooth devices.

Most phones have a class 2 bluetooth radio which is generally rated at a range of 10 m, but it can very greatly on the environment (for example, you would notice significant packet loss transmitting through even a small amount of water, such as in a person.) On the other side of the coin, the radio could detect devices up to 100 m away if there were nothing but air between the two devices.

The main problem with this is that you would have to require bluetooth to be active, which a lot of users might not have by default.

There was talk of peer to peer wifi connections, but not sure the status. Would give you some more distance than bluetooth. There is also a library

Can Android do peer-to-peer ad-hoc networking?

there is also a library from qualcomm
